Then the computer will show the wallpaper, no icons, no task bar, no start button...the cursor works in that it will move around the screen...
Also, it will not boot up into "Last Known Good"...
Reasearch found this...
This appears to have been caused by the following sequence of events:
1) You installed Windows XP Service Pack 2
2) The installation of Service Pack 2 failed due to a computer crash
during the installation which caused the automatic Service Pack Recovery
process. On next boot, you would have received an error message telling you
that the install failed, and you need to go to the control panel and
uninstall SP2 and then try re-installing it. This message may have been
dismissed accidentally or by another individual using your computer. In any
event, the Service Pack recovery process was not completed by uninstalling
the service pack from the add/remove programs control panel, and the system
is in a partially installed state which is not stable.
3) You then installed the latest security update for Windows XP,
MS04-038, KB834707. Because your system is still partially SP2, the SP2
version of this fix was downloaded and installed by Windows Update or
Automatic Updates. However, the operating system files on the system are
the original versions due to the SP Recovery process. This results in
mismatched files causing this error.
Well...this seemed like a good explanation, so I went forward as follows:
To recover the system, carefully do the following steps:
1.. Boot normally and attempt to log in to your desktop. At this point
you should get the error message listed above.
2.. Press Control+Alt+Delete at the same time to start the Task Manager.
You may get additional error messages but Task Manager will eventually
3.. On the menu bar, select File and then New Task (run).
4.. Type in "control appwiz.cpl" into the new task box and hit OK. You
may get additional errors that can be ignored.
5.. The Add/Remove Control Panel should now be running. You can close task
6.. Near the bottom of the list, find the entry titled "Windows XP
Hotfix - KB834707.
7.. Click on it and click the "Remove" button. It will take some time to
complete. Once the "Finish" button is visible, click on it and reboot your
system. If you get messages about additional software or hotfixes installed,
you can safely ignore them.
Do NOT stop now! Your system is still in the "failed SP2 install" state.
You MUST complete the SP2 uninstall, and then re-install SP2.
8.. Start the system and log in.
9.. Click on Start and then Control Panel.
10.. Click on the Add/Remove programs item.
11.. Near the bottom of the list, find the entry titled "Windows XP
Service Pack 2" entry.
12.. Click on it and remove Service Pack 2. You may get a warning about
software you have installed after SP2. Make a note of it as you may need to
reinstall some of if after the uninstall operation.
13.. After Service Pack 2 has been successfully removed, you should visit
for instructions on installing Service
Pack 2. You can get SP2 from http://windowsupdate.microsoft.com
14.. After Service Pack 2 has been successfully re-installed, you should
re-visit Windows Update to get the proper version of the latest critical
So far I have not successfully gotten Windows XP Hotfix - KB834707 removed...
I have gone thru this process 4 times and no success...
I can see SP2 sitting in the Add Remove panel...
I guess the question is, should I remove SP2???...or at least try to remove it???
Not sure what to do now...so I am looking for ideas and suggestions...
